A quantum capacitance is calculated for a single wall carbon nan otube in a eld e ect device The calculation is performed on a base of a continuum model taking into account full microscopics A general ex pression for the atomistic capacitance of a nanotube of arbitrary shape is derived The result is useful for modeling of electromechanical action of a nanotube device and for nanotube electronic...
nowadays apphcanon of nanotubes in biology and medicinal science is more investigated. nanotubes can passthroueh cell walls and transport and release drugs in special tissues. the purpose of this paper is to investigatethe interaction of a nanotube having hydroxyl functional groups (oh) with an anticancer agent. in this worktransporting of an anticancer drug named 2-(2-amino 6,7-dimethyl pterid...
One of the critical issues for the application of single-wall carbon nanotubes (SWCNTs) in nanoelectronics is the control of their electronic properties, which can be either metallic or semiconducting in their pristine form, depending on their diameter and chirality. Since all known preparative methods yield mixtures of metallic and semiconducting nanotubes, extensive research has been devoted ...
X-ray absorption near-edge structure (XANES) measurements have been performed on nitrogen-doped diamond films with three different dopant concentrations and iron-layer-stabilized carbon nanotube (CNT) structures with various diameters at the C K-absorption edge using the sample drain current mode. The C K-edge XANES spectra of these N-doped diamond films resemble that of the undoped diamond reg...
The synthesis of single-wall carbon nanotubes of desired diameters and chiralities is critical to the design of nanoscale electronic devices with desired properties. The existing methods are based on self-assembly, therefore lacking control over the diameters and chiralities. The present work reports a direct route for rolling graphene. Specifically, we found that the electrostatic deposition o...
